在 WildFly 8 中部署 EAR 应用程序时出现问题，找不到持久性单元

Question

我正在创建一个 Java EE/7 EAR 应用程序，目标 AS 使用 WildFly 8.2。我注意到的第一件事是我的 ds.xml 文件没有在服务器中定义任何 DS，我必须手动创建它。注入 EntityManage 的第二个 y 类具有以下注释：

@PersistenceContext(unitName = "DebitoAutomaticoMockDS")
private EntityManager em;

但在那之后部署 WildFly 时仍然出现以下错误：

我很困惑，因为我的持久化单元如下：

<persistence version="2.0"
   xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="
        http://java.sun.com/xml/ns/persistence
        http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
   <persistence-unit name="primary">
      <!-- If you are running in a production environment, add a managed 
         data source, this example data source is just for development and testing! -->
      <!-- The datasource is deployed as <EAR>/META-INF/DebitoAutomaticoMock-ds.xml, you
         can find it in the source at ear/src/main/application/META-INF/DebitoAutomaticoMock-ds.xml -->
      <jta-data-source>java:jboss/datasources/DebitoAutomaticoMockDS</jta-data-source>
      <properties>
         <!-- Properties for Hibernate -->
         <property name="hibernate.hbm2ddl.auto" value="create-drop" />
         <property name="hibernate.show_sql" value="false" />
      </properties>
   </persistence-unit>
</persistence>

求指点，实在找不到问题

Answer 1

@PersistenceContext(unitName = "") 中的单位名称应与 <persistence-unit name="primary">

中定义的相同

你的情况是 "primary" 而不是 "DebitoAutomaticoMockDS"。

解决方法： @PersistenceContext(unitName = "primary")
